11 Claims. (Cl. 67-7.1)

This invention relates to smokers lighters and an object is to provide alighter having improved structural features which produce a more ruggedlighter having a more general utility and a more dependable operationthan has heretofore been the case.

A further object of the invention is to provide a lighter of this typeconstructed and arranged to have the general utility of an ordinarymatch.

As heretofore usually constructed, lighters of this type, althoughsuitable for lighting cigars and cigarettes, have not been entirelysatisfactory when employed for lighting pipes or for general lightingpurposes, because the construction of the light has prevented the flamebeing positioned close enough to the pipe to light the tobacco. This hasbeen especially true of lighters having windshields around the wick toprevent the flame being blown out.

A further object is to provide an improved lighter constructed andarranged to provide both a protecting :vifidshield for the flame and asatisfactory, efficient pipe 1g ter.

A further object is to provide a lighter the main body portion of whichcan be formed from a solid block of material to produce an extremelyrugged article having a prolonged period of usefulness.

A further object is to provide an improved lighter construction in whicha single movement of the thumb simultaneously uncovers and ignites thewick.

A further object is to provide a lighter having an improved arrangementfor storing spare parts such, for example, as flints or the like.

A further object is to provide a lighter having an improved mechanismfor feeding flints to the knurled wheel or file, so constructed that noparts other than the flints themselves engage the wheel surface, wherebywear of the wheel and the flint feeding device is reduced to a lowerpoint than has heretofore been though possible and the life of thelighter greatly prolonged.

With the foregoing and other objects in view, I have devised theconstruction illustrated in the accompanying drawings forming a part ofthis specification. It is, however, to be understood the invention isnot limited to the specific details of construction and arrangementshown, but may embody various changes and modifications within the scopeof the invention.

Figs. 9 and 10 are front and side views, respectively, of one form ofextensible Wick holder forming a part of the present invention.

The particular embodiment of the present invention which is illustratedin the accompanying drawings includes a body member 11 or casing formedfrom a solid block of material 12, such, for example, as metal. Asillustrated, two fuel storage chambers 13 and 14 are drilledlongitudinally from the bottom end 15 of the block to provide twoparallel laterally spaced bores or chambers which are shown ascontaining loose cotton 16 or other material of an absorbent nature forholding the lighter fuel in the storage chambers and prevent leaking. Anintervening wick chamber 17 is formed between the fuel chambers 13, 14and in communication with them by drilling a bore in the block 12 midwaybetween the fuel chambers and parallel thereto. This bore is drilledwider than the thickness of the dividing wall between the two chambers13 and 14, so that bore 17 is in communication with both chambers 13 and14 for the common lengths of the chambers. That is, the Wick 17 isformed of a diameter somewhat greater than the distance between thesides of the fuel chambers 13 and 14 so as to provide slots 18, 19extending longitudinally along opposite sides of the wick chamber 17 andcommunicating with the respective fuel chambers so that a wick 21 in thewick chamber 17 absorbs fuel from the fuel soaked cotton in the fuelchambers 13, 14. A screen 22 extends across each slot, preferably forthe full length thereof, to prevent the cotton 16 or the like enteringthe wick chamber 17 and interfering with the movement of the wick, ashereafter described. That is, to keep the wick and cotton separate,although in sufliciently close contact that lighting fluid will bereadily transferred from the cotton in the fuel chambers 13 and 14 tothe wick in the bore or chamber 17 in all positions of the wick and itsholder.

One feature of the invention is the arrangement by which the wick can beextended outwardly beyond its normal position to facilitate lighting apipe, for example, or to provide an emergency candle, or for any otherpurpose. As illustrated, this is accomplished by providing a wick holderin the form of a tube 24 slidably mounted in the wick chamber 17 formovement from normal retracted position shown in full lines in Fig. 2 tothe projected position shown in broken lines, and preferably somewhatfarther. The wick 21 extends through the tube and has a protruding end25 at the upper end of the tube for igniting purposes, and the oppositesides of the tube are each provided with a longitudinal slot 23 throughwhich the wick is exposed and contacts the screens 22 to absorb fuelthrough them from the cotton in chambers 13 and 14. A channel 20 ismilled or otherwise formed in the top of the casing 11 from the rearside edge to form walls 20a around the front and sides and provide awindshield around the end 25 of the wick 21. The channel 20 is thus openat the rear for a purpose to be described. The wick tube 24 issufficiently loose in the Wick chamber 17 to be freely slidable, and agasket 26 adjacent the upper end of the tube 24 seats in a counterbore27 at the upper end of the wick chamber 17 and under the flange 29a onthis tube to seal the chamber against leakage at that end when theholder is retracted. The lower portion, approximately the lower half, ofthe wick holding the tube 24 is slotted as shown in Fig. 9 to providethe oppositely disposed slots 23 adjacent the communicating slots 18, 19between the wick chamber 17 and the respective fuel chambers 13, 14, soas to permit the wick to absorb fuel from the storage chambers 13, 14.The operating means for slidably extending the tube 24 is illustrated asbeing formed by an inverted U-shaped frame 28, the web 29 of whichincludes the flange 29a secured to the wick tube 24, and the arms 31 ofwhich extend downwardly and are slidably mounted in slots 32 on oppositesides of the casing 11. An enlarged finger piece 33 is formed on the endof each arm and overlies the adjacent slot 32. In order to prevent thefinger pieces from rubbing and marring the surface of the casing ateither side of the slots 32, a pin 34 extends inwardly from each fingerpiece 33 sufficiently far to engage the bottom of the adjacent slot 32and hold the finger piece out of contact with the surface of the casing11, see Figs. 1, 4 and 7. A shoulder 35 at the upper end of each slot 32engages the pins 34 when the frame 28 and wick 21 are elevated andprevents them being unintentionally raised entirely out of the casing.However, the holder and wick can be lifted entirely out of the casingfor repairs or renewing the wick, merely by spreading the arms 31 farenough for the pins 34 to clear the shoulders 35, the arms beingsufliciently resilient for this operation.

For sealing purposes a gasket 36 such, for example, as a Teflon gasket,surrounds the tube 24 above the web 29 of the frame 28 in position to beengaged by the beveled edge 37 of an inverted sealing cup 38 looselypivoted and riveted to the top 39 of a cover 41 so that it may havesufficient lateral rocking movement for the edge 37 to seat properly onthe gasket. The cover 41 is pivotally supported on a pivot pin 42 in theside walls of the end channel adjacent the open end of the channel atthe back of the casing 11. When the cover 41 is closed, as shown in Fig.1, the beveled edge of the cup 38 seats on the beveled gasket 36 with asealing engagement to prevent fuel leaking out through the wick, whilethe gasket 26 which is preferably of resilient material seals theopening around the outside of the wick tube and provides a safe sealagainst the leakage of any fuel from the wick chamber around the upperend of the wick tube 24.

The cover 41 includes a frame 43 having a slot or rectangular opening 44over the pivot pin 42, see Figs. 2 and 7, through which a pair oflaterally spaced thumb wheels 45 having toothed or corrugatedperipheries 45a project, as shown in Fig. 2. The thumb wheels 45 aresecured to a flint engaging Wheel or file 46 so that the latter will berotated when the thumb wheels 45 are actuated. The thumb wheels 45 aremounted tight on the hubs 46:: on opposite sides of the file wheel 46.The end 47 of the c6ver frame 43 extends across the thumb wheel andconnects the side chambers 43a of this cover frame, but is slightlyspaced from the periphery of the wheels so that the cover can either beraised independently of the file wheel by pressing down on the frame end47 only, or the two can be operated simultaneously by both pressing theframe end 47 and rotating the thumb wheels with a single movement of thethumb, as the edges of the wheels 45 project and are exposed above thetop edges of the side members 43a and the thumb engages both the wheels45 and bar 47 at the same time.

The cover is yieldingly held in either open or closed position by one ormore detent fingers 48 or the like which are pressed by a spring 49 intoyielding contact with a cam surface 51 on one side of the frame 43.There are preferably two of these detents as shown in Fig. 7, one foreach side member 43a. The springs 49 and fingers 48 are each housed in abore 52 in the casing, see Fig. 7. The cam surface 51 is so shaped andso positioned with relation to the cover supporting pivot pin 42 that inclosed position, as shown in Fig. 3, the spring 49 and pin 48 press thecover closed and hold the cup 38 on the gasket 37 with a sealingpressure. In opening the cover the pin 48 rides over a shoulder 53 onthe eccentric cam surface 51 to the flat 51a and holds the cover in openposition, as shown in broken lines in Fig. 2. As the cover is swung tothe closed position of Fig. 3 the shoe or fingers 48 rides along theeccentric cam surface 51 further tensioning the spring 49 and as itpasses over the bump 53 onto the flat 51b it has a sort of snap actionon the cover to close it and press edge of cup 38 against gasket 36, andthen pressure of the shoe 48 on flat 51b, being located to the right orrear of pivot pin 42 as shown in Fig. 3 will hold this cover tightlyclosed.

A flint supply channel 54 is bored in the casing 11 and extends from thebottom thereof to the top at a point adjacent the file wheel 46. A flint55 when placed in the chamber 54 is pressed against the bottom of thefile wheel by a spring pressed pusher 56 having circular or tubular ends57 and an intermediate slotted body portion 58. The pusher is yieldinglypressed against the lower end of a second flint 55a under the file wheelengaging flint 55 by a helical spring 59 compressed between the lowerend 57 of the pusher 56 and an arm 61 extending inwardly from the lowerend of a flint magazine cover 62. The spring 59 is guided by a rod 63secured at one end in the arm 61 and extending upwardly through thelower end of the pusher 56 to which it is loosely and slidably connectedby having a bent end 64 on the rod slidably engaging in the slot 65 inthe slotted body portion 58 of the pusher 56. The lower end 65a of slot65 and bent end 64 are preferably so located that the end of the slotengages the bent end and stops further movement of the flint feedingmember 56 when the second flint 55a is about half used so that the endof feed plunger 56 never engages the file wheel 46. A flint magazine isformed by a slot 66 in the back of the casing communicating with theflint supply channel 54. The pusher 56 and rod 63 are slidably insertedin the flint supply channel 54 from the bottom, and the cover 62 isslidably inserted in the slot 66 from the bottom. An abutment member 67formed by a pin or the like on the inner surface of the cover 62 isadapted to engage a shoulder 68 in the magazine slot 66, see Fig. 2, tohold the cover in proper position to close the magazine slot 66 andcause the flint pusher 56 to press the flint 55 against the face of thefile wheel 46. Below the shoulder 68 the magazine slot is formed with astop shoulder 69 to prevent the cover being unintentionally slid openpast that point when it is desired merely to open the slot 66 far enoughto renew a flint 55. As indicated in Fig. 2, the slot is wide enough tohold a number of spare flints 55b in storage. The upper head 57 of thepusher and the fiints are of substantially the same diameter as guidechannel 54 for them and therefore they prevent extra fiints 55b frompassing into this channel unless the pusher 56 is retracted or shifteddownwardly to provide sufficient space above head 57 for a flint 55b todrop into the channel. This also prevents extra fiints being jammedbetween head 57 and walls or storage space 66. Below the stop shoulder69 the slot 54 can be used to store additional Teflon gaskets or similarparts, if desired. To open the flint storage space the upper end of thecover 62 is raised by inserting a fingernail or the like under a recess71 in the cover and the spring cover is bent outwardly a sufficientdistance for the abutment 67 to clear the shoulder 68 after which thecover and pusher can be slid outwardly until the abutment engages thestop shoulder 69. When the cover 62 is slid open far enough for theabutment 67 to engage the stop shoulder 69 access to the spare flintmagazine is obtained, and such movement retracts the flint pusher 56 andits upper end 57 far enough to permit a fresh flint being placed in thechannel 54 to be pressed against the file wheel 46. If the cover isagain bent outwardly for the abutment 67 to clear the stop 69 the covercan he slid further open until the abutment 67 engages a stop shouldernear the bottom of the casing 11, in which position the lower storageportion of the slot 54 is open. When the cover and pusher are againreturned to closed position the flint is pressed into operativeengagement with the file wheel by the spring 59 and pusher 56. The cover62 and pusher can be entirely removed from the casing by lifting theabutment 67 past the lower shoulder 70, after which the cover and pushercan be entirely removed from the casing. The pusher 56 is of such lengthrelatively to the flint channel, and the pusher spring is of such size,that the upper tubular end 57 of the pusher 56 will never be pressedagainst the file wheel, thus preventing dulling of the file wheel teethwhen a flint is not in position. The arrangement is preferably such thatmore than a single flint can be placed in the supply channel 54 abovethe pusher tube 57, and feeding movement of pusher 56 will be arrestedby lower end 65a of slot 65 engaging bent-over end 64 of rod 63 whenabout half of the flint immediately against the end of this pusher hasbeen worn off, so that the pusher will never engage the surface of thefile wheel. Therefore, before the last particle of flint is used up thefresh flint must be inserted. Hence the end of the pusher never contactsthe wheel.

Fuel is supplied to the fuel storage chambers 13, 14 through the openends of the chambers at the bottom of the casing 11. In order to sealthe ends of the chambers 13, 14 the bottom of the casing has an undercutslot 75 communicating with the open ends of the fuel chambers 13, 14.Fuel can be supplied to the chambers 13, 14 through the lower endsthereof, which are normally sealed by a gasket 76 of synthetic rubber orother resilient sealing material covering the openings within theundercut slot 75 and held securely in place by a cover 77 slidable inthe slot 75 and locked in closed position by any suitable means, such,for example, as the cam lock spring plate 78 which comprises a circularportion rotatably secured to the cover 76 and rotatable by means of anarm 79 to rotate the shaped edge of the cam plate either to engage thesides of the undercut slot 75 to secure the cover closed, as shown infull lines in Fig. 6, or to release the cover, as shown in broken lines,to permit removal. The opposite side portions of this spring plate areinclined from a diagonal ridge 78a as shown in Fig. 2 forming camsurfaces which engage under the overhanging outer edges 75a of slot 75as the spring plate is turned to bring this ridge into the slot as shownin Figs. 1, 2 and 6 and compress the plate to clamp the cover tightlyagainst the gasket and provide a tight closure. When this plate isturned to the dotted position, the central ridge 78a is shifted from theoverhanging edges of the slots 75, thus relieving the clamping action onthe cover so that it may be removed.

In operation, assuming that the top cover 41 is closed, as shown in fulllines in Figs. 1 and 2, if it is desired to secure a light the cover 41is opened and the file wheel 46 rotated to ignite the projecting end 25of the wick 24 by rotating the thumb wheels 45 to the right or clockwiseas shown by the arrow in Fig. 2, and at the same time opening the cover41 by simultaneously engaging the end 4-7 of the frame 43 with the thumband thereby rotating the file wheel and opening the cover to the brokenline position shown in Fig. 2, all in one movement. This ignites thewick 23, while the cover is held open by the detent fingers 48. If it isdesired to light a pipe, the lighted wick can be extended by pushing thefinger pieces 33 on each side of the casing upwardly until the pins 34strike the shoulders 35 at the upper ends of the slots 32, to extend thewick holder 24 and project the wick, as indicated broken lines in Fig.2. In this position the flame can be easily applied to a pipe or otherarticle in the manner of an ordinary match. When the wick is returned toretracted position the cover can be closed, the finger or pin 48 ridingover the shoulder 53 on the cam 51, after which the pressure of the pin48 holds the cover closed and seals the beveled edge of the inverted cap38 against. the beveled gasket 36.

Being formed from a solid block of material, the casing 11 is extremelyrugged. The projectible wick and the different details of constructionprovide a lighter of universal use and exceptionally long life. Theinvention can be variously modified and adapted within the scope of theappended claims.
